Proverbs 3:13-18 ... Happy is the man that findeth wisdom, and 
the man that getteth understanding. 14 For the merchandise of it is 
better than the merchandise of silver, and the gain thereof than fine 
gold. 15 She is more precious than rubies: and all the things thou canst
 desire are not to be compared unto her. 16 Length of days is in her 
right hand; and in her left hand riches and honour. 17 Her ways are ways
 of pleasantness, and all her paths are peace. 18 She is a tree of life 
to them that lay hold upon her: and happy is every one that retaineth 
her.
  
Matthew 11:28-30 ... Come unto me, all ye that labour and are heavy 
laden, and I will give you rest. 29 Take my yoke upon you, and learn of 
me; for I am meek and lowly in heart: and ye shall find rest unto your 
souls. 30 For my yoke is easy, and my burden is light
